Another SketcheBook

October 13, 2020 Leave a comment

After my 6th Sketchebooks I start creating sketchebooks for my self, cutting the A4 papers, punch or glue them together then creating the cover and Sketch over it, other sketchbooks are purchased online then again I draw/sketch on it’s cover. Sample of what I made here ..

Sketch Books 12, 13 Here

Sketch Books 22, 23 Here

This one here is my 42nd Sketchebook Cover, I purchased this from AliExpress site, verey nice and small but the papers are very thin and the colors appear on the other side of the page, over all, they are doing the job.

More sketches are available in My Sketchbooks Page..

Tow Weeks with Kaggle



Several months ago I was looking for some data to test one of my projects, the search take me to KAGGLE page, I spend some time there grab some free data I want; test my project.. DONE!.

Tow weeks ago I was reading an article and the name Kaggle come across, I decide to give the page some more time. I join it, and immediately start to joined one of free courses. I am happy to be there, learning from the community I finish five free courses in Tow Weeks, they have tons of data, highly recommended it.


…… KAGGLE Team ….. Thank you ..

Sketch to Relax


This is a last night Sketch, just to break or stop thinking in codes and functions that are not working well. I think I need to stop codeing for 2-3 Days.

Python Project: Filter Numbers with a List

April 15, 2019 Leave a comment



Python: Bite 107


Filter numbers with a list comprehension

I was happy to join Pybites and start to solve the code-challenges, my problem from the first bite was that i am solving the challenges in other online python interpreter, and it looks working fine and the output seams as it should be, but once I copy the code in Pybite portal and doing the code test it fail and gives errors.

In this challenge Bite 107, after a list of numbers the task is to return the positive even number. Now in the task description it mentioned to use (elegant list comprehension; one line of code). I start to work on it, immediately it jump to my head a for loop and if each item is even and more than 0 add it to my_list, then return my_list. After coding, the output was a list with positive and even numbers in a Number-list, but it failed in the Bite test portal. WAY!.

This type of failure was against me in other challenges also, and i was just setting all the day thinking what happen!. With Bite 107 I decide to click on “Show Solution” button just to see what is wrong.

One line code:The Solution was in one line of list brackets after a return statement congaing for and if without my_list. just like that. I start smiling, and ask my self “How could i know that i can write it like this??”. Yes it is beautiful, Yes elegant and yes one line of code, and yes my-way of coding gives the answer that we want, my code pass my testing exam.

Concloguen: I think i come up with a good resource of learning python, I don’t want to read book’s but reading codes that doing things and having the alternatives of writing same code; this will help me a lot. I am not coding for NASA or in other sensitive area that processing time is essential and micro-milli seconds make difference, so one line of four-line to-me is OK. 🙂

Acknowledge: I’d like to thank Pybite community for there contribution in spreading knowledge and codes, and for this challenges. I will read the challenges, and try my best to solve them as elegant as i can, also i will not stop in one point because my code is 2 lines more than what should be.

Last thing, Bite 107 here is my code and the elegant code. Be calm and positive.



The Code:



#First: My Code
def filter_positive_even_numbers(numbers):

my_list=[]

for i in range(len(numbers)):

if (i>0 and i%2==0) :my_list.append(i)

return my_list

print (filter_positive_even_numbers(numbers))



#The optimal solution
def filter_positive_even_numbers(numbers):

return[n for n in numbers if n > 0 and n % 2 == 0]

Python Project: Draw Face

November 25, 2018 Leave a comment

Drawing Face

In this fast python code we will draw a Face using 3 circles and one line.

We need to import a library for this called turtle, and we will use functions to help us in our mission, so let’s start.

#Python #code to #draw #face

import turtle
t=turtle.Turtle()
t.speed(9) #this will set the drawing speed to 9.

t.pencolor(“black”) #you can change the color to red, blue, or any other.

# Now we will create a functions taking circle size(s), the position (x,y) and our turtle name (t)

def d_c(t,s,x,y)
t.penup() #take pen up of the canvas.
t.goto(x,y) #goto position x,y
t.pendown()

t.circle(s) # draw the circle.

d_c(t,50,25,0) # call to draw the face
d_c(t,7,5,50) #call to draw the eye.
d_c(t,7,50,50) #call to draw second eye
t.penup()

#now we will draw the mouth
t.goto(15,20)
t.pendown()
t.goto(50,20)

Python Project: Expenditure App Part 1

November 23, 2018 Leave a comment

Python Project:

Two months back I start to learn #Python “Python is a #computer #programming #language “, you can say it grabbed me very quickly. I start to read some #sample #code from the net, then downloading the requirement and after 10 working days I was writing #codes in python and doing what I love Solving #mathematics puzzles with #python’.

So I decide to contribute in training or publishing python language by posting some codes block with explaining and comments, also by developing an application so we will learn on a real example.

I am publishing some codes on my Twitter (@h_ta3kees):

https://twitter.com/h_ta3kees?s=09

and I will do the same here on my blog.

The coming posts will be about the application that we will start develop I will call it ‘Expenditure App’.

Macro on RoSe

April 11, 2013 3 comments



If you want to have a Macro shot you have to get the right lens for that, here i am using the Nikon 105mm Macro lens to take this photo, using tripod and low shutter (for indoor shots) and the lights are the key elements to a good sharp photo; a release cable is a great idea.

In this shot i am using the Nikon D90 camera and Nikon 105m lens
DSC_3975 copy
